# Tune search and SEO

Readers find your documentation in two ways: they search inside your site, or a search engine sends them to a page.
Redocly supports both paths.
It builds a search index from your content at build time, and it generates the metadata, sitemaps, and page structure that search engines read.

## Search inside your site

Redocly indexes your Markdown, API descriptions, and code samples during each build.
You choose the search engine and tune what the index includes.

- **[Site search](/docs/platform/navigation/search)** - How Redocly processes your content and serves search results
- **[Search configuration](/docs/platform/config/search)** - Choose a search engine, add facets, and exclude content from the index
- **[Search API](/docs/platform/customization/search-api/openapi)** - Query the search index from your own applications

## Search engines and SEO

Redocly generates sitemaps, canonical URLs, and structured metadata for every page.
You control titles, descriptions, and indexing behavior per page or across the site.
